The arcs all equal to the third of the perimeter since equilateral triangle divides them like this.
So we need to find a perimeter but we are only given the area.
Let's review,
That means that from area we area able to calculate radius.
Insert the numbers,
Then use the perimeter formula to calculate perimeter since radius is known,
Now divide perimeter by 3 to get length of AB arc.
Hope this helps.
Y varies directly with x means y = kx or y/x = k where k is the constant of variation (slope)
Using
we can plug in the x and y values from the given points.
We get the following proportion:
32 = 4y ← cross multiply
8 = y ← divide both sides by 4
ANSWER: y = 8
Using
We get the following proportion:
32 = 4y ← cross multiply
8 = y ← divide both sides by 4
ANSWER: y = 8
